Synopsis of the American Species.^ 



Com. Char. Above bluish-plumbeous, the penicillate scapular jdumes more hoary ; remiges 

 and rectriees slate-color. Lower parts longitudinally striped with black and white. Young with- 

 out any plumes, and with the colors much duller, the pattern badly defined. 



A. Tihiic and Jmrihr nf fhe wing jyurplish-cinnamon or rufous. 



1. A. occideutalis. Pileum and occipital plumes, with rest of head, white ; forehead streaked 



with black. Sometimes whole plumage pure white! Culmen, 6.40-6.75 ; tarsus, 8.00- 

 8.75 ; wing, 19.00-21.00. Hab. Florida to Southern Illinois ; Cuba ; Jamaica. 



2. A. Wardi. Similar to A. occidentalis, the white phase apparently undistinguishable, but 



culured phase c<.imliining the head-pattern of A. hirodiaa with light-colored under-parts 

 and large size of '' WUrdenuinni." Culmen, 6.50-7.00 ; larsu.s, 8.50-9.00; wing, 20.00- 

 20.50. Hnh. Southwestern Florida. 



3. A. herodias. Pileum and occipital plumes lilack ; forehead ,and central feathers of the 



crown white ; culmen, 4.30-6.25 ; tarsus, 6.00-8.25 ; wing, 17.90-20.00. Hah. North 

 America in general ; Middle America ; (Jalapagos ; Venezuela ; West Indies. 



1 The terms "mental apex," "malar apex,'' and "frontal apex" are here employed to denote the 

 apices, or points, of the feathering of tlic liead at the base of the bill. 



^ Of the exotic species properly referable to this genus, we have seen only A. purpurcn, Linn. (Euro- 

 pean). Tliis seems to be strictly congeneric as to details of form, except that the claws are much length- 

 ened ; but it has a very different system of coloration.
